A
Warning
The potential for an accident increases when operat-
ing an aerial platform that is damaged or malfunction-
ing. Death or serious injury could result from such
accidents. Do not operate the aerial platform if it is
damaged or malfunctioning.

tions.
Note
When checking the turntable rotation function in the
counterclockwise direction, the turntable will rotate to-
ward you.

trols:
1. Push the emergency stop button inward to turn off
the electrical power.
2. Test opetate the lower control functions to make sure
they no longer operate.

controls:
1. Place the battery disconnect switch, the emergency
stop switch, and the start switch in the on position.
2. Hold the emergency power switch down and the

Figure 8.8 – Tires and Wheels
The aerial platform has non-marking foam filled tires.
Foam filled tires do not have a pressure decal or a valve
core.
To inspect foam filled tires and wheels:
1. Check the wheel lug nuts to see that none are miss-
ing, damaged, or loose.
2. Carefully inspect for large holes or cuts where foam
is coming out of the tire.
3. Look for large imbedded objects, such as angle iron,
that can rip a tire open.
Note
Punctures caused by bolts, screws, or nails are not a
problem for foam filled tires.
Lower Control Station
With no personnel in the platform, test the operation
of each control from the lower controls (refer to Figure
8.9).
